The lens is the part that delivers the light to the sensor. The lens can have different apertures and focal lengths. These influence how the final image will look.
The lens is a crucial part of the camera system that determines how the image is captured and recorded. The aperture of the lens controls the amount of light that enters the camera, while the focal length of the lens determines the field of view and perspective of the image. Different types of lenses can be used to achieve different visual effects, such as a wide-angle lens for a broad perspective or a telephoto lens for a close-up shot.
